1) A TV Station received on more than one channel (when it
changes channel, but retains its identity) may be counted
once for each channel, excluding change in offset on the
same channel. Simultaneous reception of the same
station on more than one channel is usually a receiver
problem only, though you may present evidence to the
contrary. An FM station may be counted again when it
deliberately changes frequencies, or varies more than 100kHz
from its normal frequency. DXers should be certain
they are not counting receiver images or mixing products.
2) Stations operating successively on the same channel in a
single city what are clearly unrelated (i.e., with different
call letters and a hiatus in occupation of the channel, or
non-renewal of the first station's license) are counted as
3) A move in a station's transmitter location does
not allow it to count as a new station unless the
CITY OF LICENSE also changes. Thus, a station starting
in a small city and later moving both transmitter and
identity to a larger city, if received during both phases of
operation, will count twice. Stations moving antenna
from downtown to suburbs, for example, with no change in the
city of license, count only once. The addition of a
city to a station's identity (multiple city station
identification) does not count as a new station.
4) A change in call letters per se is not sufficient reason
to count that station as new, whether or not a change in
ownership is involved in a continuously operation station.
Power lever or changes in power alone shall have no bearing
on these guidelines.
5) Sharetime stations (rare cases of two stations in the
same coverage area sharing the same frequency at different
times of the day) count as one if they share their
transmitter; individually if they have separate transmitter
6) DX received via cable TV may be counted if the station
was received off the air on its original frequency at the
CATV headend, from which distances must be measured.
TOTAL INCLUDING CATV MUST BE SPECIFIED.
7) The precise location of the transmitting antenna shall be
the determining factor in computing the DX path distance and
tallying the number of political units received.
8) Verifications are not required; however, contributors
must be reasonably certain that all stations claimed were
received. Those totals limited to verified only should
be labeled as such.
9) DX obtained by recording only, and not witnessed at the
actual time of the reception, is eligible -- so long as the
contributor himself chose the frequency and prepared the
recording apparatus. When more than one DXer is
present at a DX reception, even as a visitor to another
DXer's shack, only those having an active part in the
reception may claim the DX.
10) Translators and experimental stations, as well as
unlicensed outlets such as pirates and clandestines, are
eligible. Harmonics of TV video signals are eligible
if the fall within another TV band, and those of FM stations
are eligible if the harmonics fall within the FM band.
But utility stations monitored on FM or TV, and CATV
radiation, do not count.
Note: The above guidelines are to be used for
reporting to VUD columns. Feel free to count your
station totals any way you like in your own log, but please
follow the above guidelines for WTFDA purposes.
WTFDAers come from varied backgrounds and differ widely on
how to count station totals; without the above, it would be
like comparing "apples an oranges" when reading DX report
columns. These are essentially the same guidelines in
use since the WTFDA began, and comments on them are always
welcome--but remember, unless reporters follow the same
standard in counting stations, it's very hard to compare
